What problem are you facing?

I am following the official document at https://www.mongodb.com/docs/manual/core/csfle/tutorials/aws/aws-automatic/ (which is not compatible with the latest client version...).

I was able to create the data key, but when trying to connect to mongo I am getting cryptic error:

 

```

const timeoutError = new MongoServerSelectionError(
                             ^
MongoServerSelectionError: connect ECONNREFUSED ::1:27020
    at Timeout._onTimeout (/Users/omerlh/dev/stripe-event-handler/node_modules/mongodb/src/sdam/topology.ts:591:30)
    at listOnTimeout (node:internal/timers:564:17)
    at processTimers (node:internal/timers:507:7) {
  reason: TopologyDescription

{     type: 'Unknown',     servers: Map(1) \{ 'localhost:27020' => [ServerDescription] }

,
    stale: false,
    compatible: true,
    heartbeatFrequencyMS: 10000,
    localThresholdMS: 15,
    setName: null,
    maxElectionId: null,
    maxSetVersion: null,
    commonWireVersion: 0,
    logicalSessionTimeoutMinutes: null
  },
  code: undefined,
  [Symbol(errorLabels)]: Set(0) {}
}

```

The client works and connects with no issues when `autoEncryption` is not specified.

 

This is my code:

```
const credentialsProvider = fromNodeProviderChain();

constcredentials = awaitcredentialsProvider();
returnMongoClient.connect(`${uri}/${dbName}`, {
autoEncryption: {
keyVaultNamespace,
kmsProviders: {
aws:

{ accessKeyId:credentials.accessKeyId, secretAccessKey:credentials.secretAccessKey, sessionToken:credentials.sessionToken, }

,
},
schemaMap: {
// eslint-disable-next-line @typescript-eslint/naming-convention
'db.data': {
bsonType:'object',
encryptMetadata:

{ keyId: [newBinary(Buffer.from(dataKey, 'base64'), 4)], }

,
properties: {
someKey: {
bsonType:'string',
properties: {
policyNumber: {
encrypt:

{ bsonType:'int', algorithm:'AEAD_AES_256_CBC_HMAC_SHA_512-Deterministic', }

,
},
},
},
},
},
},
},
});
```

What driver and relevant dependency versions are you using?

Driver - 4.11.0
mongodb-client-encryption - 2.3.0
server - latest one installed by brew
